Nice try, but that number for turnovers forced belongs to Memphis. Detroit forces 13.1 per game -- the same number they give up. Look again:

Moreover,
Miami is outscoring opponents by 6.5. Detroit is outscoring opponents by 3.9. Edge: Miami.
Miami is holding opponents to 42.7% on FG. Detroit is holding opponents to 43%. Edge: push.
(Meanwhile, Miami shoots 48.6% compared to Detroit's 43.0%...)
Miami is securing 51.5% of available rebounds. Detroit is securing 52.0% of available rebounds. Edge: push.
You give gross numbers, but the Heat play a much faster game than Detroit does --> more possessions --> more shot attempts --> more rebounds by both teams.
Not that I put a lot of stock in regular season statistics, but you've got to look at the whole picture.
